Automobile door lock

ABSTRACT

A locking lever is pivoted intermediate its length on a doorcarried mount, being operated at opposite ends by internal and external linkages. A transmitter is pivoted on the lever to depend into or out of the path of inside and outside operators in the respective unlocked and disabled or locked condition of the lock. The locking lever has an automatic locking kick-off and reset slide mounted thereon; and in one position of its sliding adjustment on the lever the slide kicks the lever to unlocked position when the door closes and latches. In another position, to which the slide is actuated by an operator, the slide fails to kick the lever and the door latches shut in a locked condition.

FIGQIO ATTORNEYS SHEET 5 BF 5 INVENTOR JOSEPH P ICKLES ATTORNEYSAUTOMOBILE noon LOCK BACKGROUND OF THE INVENTION 1. Field of theInvention The invention relates to automobile door lock structures and,more particularly, the overrunning or free-wheeling class thereof inwhich a manual inside and/or outside operated handle or push button is,in a locked condition of the structure, disabled from transmittingunlatching effortto a latch holding detent. This type of locking actionis to be distinguished from that of a lock in which the operator ispositively blocked by meanS of some sort from operating the detent tounlatch the lock.

2. Description of the Prior Art The most pertinent prior art US. Pats.of which I am aware are Shay No. 3,359,026 of Dec. 19, 1967, SlatteryNo. 3,384,404 of May 21, 1968 and Dale No. 3,388,940 of June 18, 1968.These relate to arrangements to disable a manual operator byfree-wheeling or overrunning it in relation to a detent, and in ageneral way to locking kick-oif and reset means. However, none of thesepatents show or suggest such provisions of a medially pivoted,rocker-type locking lever or control arm which is manually operableselectively from an inside push button, the outside key-operated linkageand the inside remote operator. Nor do they disclose an automatickick-off and reset member slidably mounted to shift bodily on thelocking lever in a single stroke between kick-off and reset positions,thus affording an improved and simplified kind of keyless locking ashereinafter described.

SUMMARY OF THE INVENTION The lock of the invention affords, essentiallyby reason of a single, medially pivoted control rocker arm or lookinglever equipped between its ends with a pivotally depending transmitterelement, and with a kick-off and reset slide adjustable lengthwise onthe arm, the abilities to automatically lock an automobile door closed,without key and by performing two simple sequential preset steps. Anautomatic damage-preventing kick-off from locked to unlocked conditionwhen the door is slammed shut is also a feature. The manual unlockingand locking actions may derive from either the usual push button at theinside door garnish molding or the usual inside-operated remote controlhandle, just as theymay result from the operation of an outside tumblerand key lock. Moreover, keyless locking from the outside may be hadwithout the need to hold the outside handle or finger button depressedwhile slamming the door shut with the lock previously set in a" lockedcondition. In all cases the locking action is a free-wheeling one, not ablocking one.

The parts are extremely simple and inexpensive, yet adequately sturdy,inasmuch as neither the locking lever or rocker nor its associatedtransmitter is subject to appreciable stress in the unlocked, forcetransmitting condition of the lock. Of course, neither are subject toany stress at all in the locked, free-wheeling or overrunning condition.The locking linkage is shown herein as beinG applied to an automobilelock of the type in which a forked latching member or plate is pivotallymounted to straddle a keeper pin in the door-latched condition. However,a similar arrangement is obviously applicable to a lock of the rollingbolt type.

DESCRIPTION OF PREFERRED EMBODIMENTS The simpler version of the improvedlock of the invention, generally designated by the reference numeral 10,comprises, in common with other locks of generally similar type, amounting and housing structure 11 in the form of a U-shaped plate havingparallel side flanges 12, 13. The plate has holes 14 for the receptionof screw or bolt means by'which it is rigidly attached to an innerpanel, not shown, of an automobile door, these openings being in a mainbody plate portion 15 of main housing plate 1 1 and an upper flange orear formation 15 thereof. Housing flanGe .13 has an aperture 16 (FIG. I)which goes over a keeper bracket 17 fixed on the automobile door post(not shown) when the door is closed; and bracket 17 carries a keeper orstriker pin 18. In the usual fashion, pin 18 is straddled by a forkrecess 19 in a latching plate 20 of the lock when the lock is wholly orpartially latched, and the plate 20 is strongly urged in thecounterclockwise direction, as viewed in FIG. 1, by a spring 23 anchoredto housing portion 15, encircling the pivot 22 and acting in a notch 24in the plate. Typically, plate 20 is formed to provide tooth-likeabutments 25, 26 on its periphery. The casing or housing structure 1 1is completed by a closure plate 27 (FIG. 2) suitable secured rigidly tothe remainder of the housing, as at the flanges 12, 13.

A latch-engaging detent, generally designated 28, is in the form of abell crank of inverted V-shape, which is pivotally mounted by a pin 29to the body portion 15 of housing 1 1, adjacent the upper end of thelatter. The detent 28 is strongly urged clockwise (FIG. I) by a coilspring 30 anchored to the housing portion and acting against the detentat an offset end 31.

One arm 33 of detent 28 is thus urged clockwise against latching plate20 and, in the latched condition of the latter of FIG. 1, contacts. theplate abutment 25 to hold the lock latched. The other arm 34 of detent28, in this position of the latter, depends closely adjacent and justwithin the housing flange 12. Arm 34 is provided with a verticallyelongated slot 35 in a laterally offset portion 36 thereof, for apurpose which will appear. An essentially important feature of theimproved lock resides in an elongated locking control rocker arm orlever 38 which is pivotally mounted, as by a pin 39,0n the housingclosure plate 27, which arm 38 is in a vertical plane between the plate27 and the detent 28. The pivot point at 39 is at the approximatelongitudinal center of arm 38.

As best illustrated in FIG. 1, rocker arm 38 terminates at its left-handend in a portion apertured at 41 for connection with an appropriatelinkage (not shown) which is actuable by an external tumbler and barreltype, key operated lock. Manipulation of the key in unlocking lock 10 iseffective to swing locking control arm 38 counterclockwise to theposition of FIG. 1, in which the lock 10 is shown as being latched bydetent arm 33. Clockwise operation of arm 38 by the key places controlarm 38 and the lock in a disabled and locked, freewheeling oroverrunning condition in respect to its inside and outside operators, aswill be described.

The opposite or right-hand end (FIG. 1) of rocker arm 38 is formed, asby aperturing at 42, for engagement by a linkage from the usualpushbutton means (neither shown) at the inside window trim molding ofthe automobile door; and clockwise and counterclockwise swing of arm 38through such an inside locking control agency places lock 10 in therespective locked and unlocked conditions just described.

Locking contrOl arm '38 is also actuable directly from the usual insideremote control or door handle by means of a bell crank or leverarrangement, generally designated 44, hereinafter described in detail;and actuation of the arm 38 by this means also conditions the latter andits transmitter (to be described) in the same way as does actuation bythe outside barrel lock key and the molding push button.

An over center type of coiled spring 45, anchored to housing closureplate 27 and acting on control arm 38 at 46, provides the usualover-center snap action in the pivotal shift of arm 38 in one directionor another.

Locking control rocker arm 38 has a force transmitter or contactorfinger 48 pivotally mounted in depending relation thereto ata pointbetween arm pivot 39 and the left-hand, key-operated end of the arm, asviewed in FIG. 1. This finger is provided adjacent its lower end with anintegral, transversely offset ear 49 which, as illustrated best in FIGS.1, 2 and 4, extends laterally into the vertically elongated slot 35 ofthe depending arm 34 of detent 28. Transmitter finger 48 has arelatively loose depending pivotal connection at its top to the arm 38,as at an offset 50 received in an opening 51 (FIGS. 2 and 4) in arm 38.

As best shown in FIG. 2, the outside unlatching operator of lock 10 isin the form of a lever or arm 52 adapted to be connected at an opening53 adjacent one end thereof by appropriate linkage means (not shown) toan external operating handle, button or like means on the door adjacentits key lock. Actuator 52 is pivotally mounted by a pin 54 on a lateralear 55 offset from housing closure plate 27, the pin also serving as apivot for the inside or remote control unlatching operator, as will bedescribed.

Outside operator arm 52 is bluntly T-shaped in outline, being formedintermediate the length thereof to provide an offset nose 56 which, inthe neutral position of the operator shown in FIG. 2, lies justoutwardly of the offset ear 49 of the transmitter 48. Accordingly, aclockwise motion (FIG. 2) of outside operator arm 52 about its pivot at54 causes transmitter 48 to be swung to the right by operator nose 56,or from the solid to the dotted-line position of FIG. 1. Thus, if lock10 is in the latched and unlocked or operative condition of FIGS. 1 and2, with the transmitter ear 49 in the slot 35 of the depending detentarm 34, detent 28 is swung counterclockwise (FIG. 1) to release itsother arm 33 from holding engagement with the abutment 25 of latchingplate 20.

Accordingly, the plate is urged counterclockwise by spring 23 to anunlatched position, in which the holding or keeper recess 19 of thelatch plate is released from the door postmounted keeper pin 18. Thesame occurs in the event detent arm 33 has been engaged by the secondabutment 26 or plate 20, in a condition in which the door is butpartially or safetylatched.

In the unlatching movement of outside operator 52 the latter swings fromthe solid to the dot-dash line position of FIG. 2, i.e., clockwise aboutits pivot at 54. counterclockwise movement of operator 52 is limited bya rounded nose formation 57 on the end of the operator opposite that atwhich it is controlled, the formation having stop engagement with theoutside of housing closure plate 27.

An inside or remote control actuated unlatching operator arm of lock 10is designated 58. It is in the form of a hookshaped bail pivoted by pin54 on the casing part 55 in common with, but directly above, the outsideoperator 52; and the inside operator 58 has an actuator nose 56' shapedidentical to the nose 56 of outside operator 52. These two nose partsare vertically superposed in identical register, as viewed in FIG. 2,when in neutral unactuated position.

As in the case of outside operator 52, upon a clockwise swing of insideoperator 58 from the solid to the dot-dash line position of FIG. 2, theoffset transmitter ear 59 is engaged and detent 48 is pivotedcounterclockwise, unlatching the lock,on the assumption offset car 49 isin a vertical relation to detent arm slot 35 to be engaged by the insideoperator 58, i.e., that the structure is in an unlocked condition.Again, this is determined by the position of locking control rocker arm38. When the latter raises, both of the operators 52 and 58 free-wheelpast it and are disabled as to unlatching effect.

The arm 38, in addition to being controllable by non-unlatching outsidekey means (at 41) and inside push button means (at 42), may also beselectively positioned, with the same results, by the inside or remotecontrol handle which actuates inside operator arm 58 and lever unit 44.

As best shown in FIG. 3, this may be through the agency of a small bellcrank 60 pivoted by a pin 61 on a laterally offset ear 62 which isstruck from housing closure plate 27. One arm 63 of crank 60 is shown asbeing provided with an opening at 64, where it maybe operativelyconnected by a suitable linkage (not shown) to the inside remote controlhandle of the door. This is done in such a fashion that a movement ofthe handle in a non-unlatching direction will lock the door. That is,bell crank 60 is swung clockwise about its pivot 61 (FIG. 3) in thislocking action.

The second arm 64 of bell crank 60 is forked at 65 to straddle a reducedwidth portion 66 of control member 38, just inwardly of its push buttonoperated end at 42, as shown in FIG. 1. A clockwise movement (FIG. 3) ofbell crank 60 causes the control arm 38 to be swung clockwise (FIG. 1)about its pivot at 39, with the result that transmitter 48 is lifted toa disabling position, out of the path of the operators 52 and 58. Whenthe lock is unlatched from the inside of the door, or when the insideoperator is moved toward a neutral position short of its unlatchingposition, a reverse action of hell crank 60 on arm 38 occurs and theparts are restored to the position of FIG. 1.

It is evident that, as embodied in the structure of FIGS. l-6, theinvention affords an automobile door lock which is structurally of avery simple character, in which all of the essential unlatching, lockingand unlocking actions involve the use of a transmitter-carrying rockertype locking lever or arm member, operated in coaction with a pivoteddetent and inside and outside operators, which operators act directlyadjacent one another in parallel planes, with the locking leveroperating in a plane at to said planes.

A more refined and versatile version 70 of the improved lock appears inFIGS. 7-18, inclusive, of which FIGS. 10, 11, 16, 17 and 18 supplementin a clearer way the relatively cornplex showing in FIG. 7 of the entirecombination of parts. For simplicity a number of component housing,actuator, latching and other parts which are identical, or basicallycorrespond, to parts appearing in FIGS. 1-6 are designated bycorresponding reference numerals, primed, and further descriptionthereof, and of their function, will be dispensed with. Further in theinterest of simplicity, 'certain provisions illustrated and described inFIGS. 1-6, for example, the inside or remote controLoperated bell crankor lever means 44, are not shown, though actually present, in order notto obscure other features.

A special latch holding detent or pawl of the lock 70 as best shown inFIG. 11, is generally designated by the reference numeral 72. Likedetent 28, it comprises a latching dog or arm 73 releasably engageablewith the latch members shoulder 25' to hold the lock in the latchedposition, and the arm 73 carries a laterally offset kick-off lug 74 fora purpose to be described.

The detent 72 is, generally speaking and as best shown in FIG. 11, ofinverted V-shaped outline, and is pivotally mounted on one of the lockhousing walls by means of a transverse pin 75. A coiled operating spring76 encircles this pin, one end of the spring being housinganchored, asin the first form. The opposite spring end 76' hooks around a lipportion 77 on and adjacent the fork of detent 72, in a manner tonormally urge the latter in the clockwise direction, as viewed in FIG.11.

The detent provides a downwardly depending, integral hook-shapedactuator arm 78, through the agency of which the detent is swingablyoperated by one or the other of the two horizontal actuators 52, 58'through an intermediate agency borne by the transmitter, as will bedescribed.

A special rocker type locking arm or lever member, generally designatedby the reference numeral 80, is pivoted by a pin 81, at its approximatemid-point, between the housing walls, this locking arm having apertures82,83 to receive, respectively, operating connections (not shown) to theusual door key lock and to the push button normally mounted through theinside garnish molding of the door. Manipulation of either of thesecontrols swings locking member 80 pivotally about its axis between thelatched and locked condition of FIG. 16 and the opposite condition ofFIG. 17, i.e., the unlatched and unlocked condition. FIG. 18 showsanother, reset condition in which the lock has been unlatched, but thelocking rocker arm has been placed in a locking position,from which itmust be manually shifted or automatically kicked off.

Upon one arm portion of locking member 80 (right hand in FIGS. I6-18 andleft hand in FIG. an elongated, generally horizontal slot 85 is formed,past which slot the lug 74 of detent 72 moves when the latter goescounterclockwise'from latch holding position to latch releasingposition. The other arm portion of rocker 80 is provided with arectangular opening 86 for a purpose to be described.

In addition, member 80 is provided with an integral, downwardlyprojecting lug 87 of L-shaped outline, including (FIGS. 9 and 10) ahorizontal offset at 88 and a short leg portion 89 depending from thelatter. A snap-over type coil spring 91 having one end anchored to ahousing plate and the other end anchored to a portion of the locking arm80 adjacent its slot 85 exerts the usual effort of snapping the arm overcenter in its clockwise or counterclockwise action.

The specially shaped lug 87 of the locking lever or arm 80 serves topivot a downwardly depending transmitter member 92, as at a circularaperture 93 of the latter which is slipped over the rocker arm lug 87,the transmitter 92 swinging freely from this pivotal mount. Thetransmitter 92 is provided with a laterally extending, verticallyelongated flange 94 which, as illustrated in FIG. 9, is of sufficientwidth at its top to extend behind the depending integral hook arm 78 ofdetent 72, so that in the unlocked condition a counterclockwise swingingof transmitter 92 (FIGS. 7, 16, 17 and 18) by either of the outside orinside manipulated actuators 52', 58, respectively, will cause thetransmitter flange 94, in engaging detent arm 78, to swing the detent 72counterclockwise, thus releasing the latters holding arm portion 73 fromlatching engagement with the shoulder 25' of latch member.

The transmitter 92, unlike transmitter 48 of the first embodiment, isalso swung by outside actuator 52 when in a locked position, but withoutoperating detent arm 78. It is for this reason that that arm is givenits hooked outline appearing in FIG. 11, and for the same reason theflange 94 on transmitter 92 is also specially shaped. As best seen inFIGS. 9 and 10, the flange 94 is vertically slitted at 95 intermediateits width and bent rearwardly to one side of the slit to afford a shortforce transmitting heel 96. This heel is engageable with and operatesdetent arm 78 when lock 70 is unlocked at the transmitter, i.e., whenthe latter is lowered by lever 80, but fails to swing sufficiently toengage and operate arm 78 in the locked condition (transmitter up), asWill be described further in reference to FIGS. 16 and 18. Otherprovisions hereinafter described are made at the levers locking,transmitting and reset slide for kicking off lever from locking tounlocking condition, also to pre-set thelever for automatic locking. Theslide is designated 98 and is also later described.

To the extent that the operation of lock 70 resembles that of lock 10,the transmitter 92 may be lifted by locking lever 80 from the unlockedposition of FIG. 18, in which its heel 96 can drive detent 72 to latchrelease position, to that of FIG. 16, in which its heel 96 fails toengage detent arm 78. In this case the detent 72 may not be actuated andreleased by the outside actuator, the transmitter 92 being disabled andfree wheeling in respect to the detent. Transmitter 92 is lifted bylocking arm 80 upon a clockwise movement of the latter about its pivotat 81.

As indicated above, the lock 70 is completed by the special lockingkick-off and reset slide 98 on locking lever 80, and is bestillustrated, per se, in the perspective view of FIG. 15. As associatedwith lever 80 in the manner shown in FIGS. 10 and 16-18, it has agenerally horizontal sliding action lengthwise of the lever, undersnap-over assistance by an over-center coil spring 98' whose ends anchorto the slide and the locking lever. Slide 98 is supported solely by andat a side of locking lever 80, being provided with an integral offset,kick-off transmitter lug 99 adjacent one end thereof. This lug extendsinto the open-ended slot of the locking arm, and is of sufiicientlateral extent to be overlie and be in the path of the detent lug 74when the lock 70 is in its latched and locked position of FIG. 16, i.e.,with the locking lever 80 fully rotated clockwise about its pivot at 81to disable the transmitter 92. In this position the reset lug 99 ispositioned directly above detent lug 74, so as to be moved upwardly whendetent 72 is swung counterclockwise.

This is also true in an unlatched and locked condition in which the lock70 may be placed by operating locking lever 80 counterclockwise when thedoor is open and the detent portion 73 rests atop the latch plateabutment 26', in the manner of FIG. 18. Accordingly, if the door is nowslammed shut without further manipulation the latch plate 20', inrotating counterclockwise under the influence of spring 23', causes thedetent lug 74 to upwardly engage the overlying kick-off lug 99 of slide98, so that the latter swings locking lever 80 counterclockwise to itsunlocked position. This happens as latch plate 20 engages the lockskeeper pin and swings to a latched but unlocked position, i.e., in anautomatic locking kick-ofi action.

Locking and reset slide 98 is provided (FIG. 15) at its end opposite lug99 with a second offset lug 100 at to the slide; and lug is received inthe rectangular opening 86 of locking member 80, it being noted that inthe case of both of the lugs 99 and 100 there is space for some slightvertical play in slot 85 and hole 86, respectively. The opening 86 andslot 85 are of sufficient horizontal extent to permit the slide 98 toshift horizontally on lever 80 from the kick-off position of FIGS. 16and 17 to a reset position of FIG. 18, and vice versa, and the verticalclearance allows for the swing action of locking lever 80.

Finally, slide 98 is formed to provide a third laterally offset lug 101paralleling and in horizontally spaced relation its lug 100, but of lesslateral extent than the latter; and an upright kick-ofi' and resetcontrol ear 103 upwardly integral on transmitter 92 extends between lugs100 and 101 for apurpose to be described. An offset ear 62' on thehousing plate 27 (FIGS. 8 and 9) pivotally mounts an inside, or remotecontrolled lever or hell crank unit, not shown but like the unit 44 80in the manner previously described.

FIG. 17 illustrates one manner in which the slide 98 may be actuated,with the latch plate 20 spring-swung counterclockwise to an unlatchedposition, and locking lever 80 being swung clockwise to its lockedposition. As indicated above, if the slide 98 were in the position inits position to the right on lever 80, as illustrated in FIG. 16 (butnot in FIG. 17), this would result, when the door is swung shut, in thelatching and automatic unlocking of lock 70. However, an automaticretention of the lock in its locked condition as the door is closed,accompanied by latching, is possible with the lock parts disposed inlocking preset position.

This simply involves, with locking lever 80 operated clockwise, as by agarnish mold push button and latch plate 20 in release position, anoperation of one or another of the manual operators 52' and 58' in anunlatching direction, thus to engage the transmitter 92 and swing itcounterclockwise, as viewed in FIG. 18. The result is that, although thetransmitter has been elevated by locking lever 80 out of position toengage detent actuator arm 78, its mentioned swing causes the resetcontrol ear 103 of transmitter 92, in engaging offset lug 100 of theslide 98, to shift the latter bodily to the left on locking lever 80.Hence the slides opposite lug 99 goes from a position overlying thedetent lug 74 to a position at one side of the latter. Lock 70 is nowpreset forautomatic locking, without further manipulation by the driverwhen the unlatched and open door is swung closed, due only to theclockwise swinging of locking lever 80 and the manipulation of anoperator 52 or 58 in that chronological sequence. In going closed, thelatch plate 20 cams detent 72 upwardly counterclockwise, but the lug 74of the detent misses contact with reset lug 99 of slide 98, and as aconsequence the locking lever 80 remains in its clockwise-swung positionof FIG. 18, having been disabled at lugs 74 and 99.

With the lock thus latched and in locked condition, when the lockinglever 80 is swung counterclockwise to unlocking position, as through theagency of an outside key-operated linkage, the transmitter 92 swingsclockwise about its pivot on the locking lever in being shifteddownwardly by the latter; and the clockwise transmitter movement causesits reset car 103 to engage the intermediate lug 101 on slide 98. As theswing is continued, ear 103 thus moves the slide to the right, as viewedin FIGS. 16-18, thereby restoring its kick-off and reset lug 99 from itsdisabled position in relation to detent lug 74 to its operative kick-offposition overlying lug 74. Lock 70 is now unlocked and, if unlatched asin FIG. 17, ready for preset to automatic locking by operation of thelever 80 and an operator 52' or 58 in the fashion described above.

Should it happen that, with the lock placed in its stated locking presetcondition by the successive contemplated manipulations of lever 80 andan operator, the operator 52' or 58' should unnecessarily be helddepressed, nothinG happens inasmuch as the detent operating arm 78simply idles relative to the operators and the transmitter 92 as latchplate 20 goes to latching and locking position.

' The lock of FIGS. 7-18, inclusive, affords, in addition toadvantageous features and actions had in common with the form of FIGS.1-6, inclusive, a geometrically simple yet reliable combination of asinge reset slide on a medially pivoted locking lever of the rocker armtype, in which a single rectilinear shift of the slide on the lever froma righthand limit (FIGS. 16 and 17) to a lefthand limit (FIG. 18), andvice versa, conditions the lock 70 for automatic kick-off from lockedcondition and/or for nullification of the kick-E and placing the lock ina latched position without disturbing its locked state. These actionstake place without any manual effort being exerted on the slide otherthan through lever 80, through an operator 52' or 58', and/or consequentto the effort of closing the door.

What is claimed is:

l.
